 Here's my early Christmas present and the result of many hours of work!
 One of the absolute classics and still one of my favorite demos has
 now been fixed to run properly on all Amigas!
 Patching the parts took quite a while as there are many of them.
 And then there were the timing problems in the intro...
 To fix these I had to:
 - create code to patch the disk version to store timing data
 - use that data to emulate A500 speed
 - watch the intro over and over again the check the timing

 It was long and hard work, I hope you appreciate it! The timing
 bugs completely destroyed the intro as it sure doesn't look good
 when the missiles fly through the space ship without destroying it.

 There also was disabled code in the demo to skip the intro, as I did
 not want to watch the intro all the time when patching all the parts
 I simply added an option to skip it.

 Speaking of patching the parts, the line tunnel had a bug on fast
 machines that kept me busy for a while. That the problem didn't occur
 on any of my machines didn't make it any easier but in the end
 a lot of guess work paid off and I fixed the problem!

 Special thanks to Frequent/Ephidrena for testing.


 Now there's just one other iconic demo left which REALLY deserves a
 proper fix. Which means: Hardwired will follow next!

 To quote myself: "Classics should run properly. Everywhere."

 Merry Christmas everyone.
